Hi, In a sixteen node cluster , I need to add <totem token="20000"/>. It needs the cluster nodes to be rebooted. In the test lab ( three node clusers) I modify this parameter rebooting one node at a time. Each node has zen guests. So before rebooting , moving guests to different node. In that way the guests are not being effected for the change over. Is it ok to reboot the server one at a time or it needs the whole cluster nodes down then bring up one by one? Heard that for this parameters, it is suggested to bring down the whole cluster node, then bring up. Pl. advice. Thanks again. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
